【正文】 ：祈使句，and/ then/or +一般將來時的簡單句。其中“or”解釋為“否則”，“and/then”解釋為“然后”，根據(jù)句意選擇D?！纠?】We should leave early tomorrow morning，________ we won39。t get there on time.A. so B. but C. or D. and【解析】答案是C。連詞or在句中表示“否則，不然”，轉(zhuǎn)折所導致的結(jié)果；so表示結(jié)果；前后對應，and是并列關(guān)系的連詞；but表示轉(zhuǎn)折與上文相反?！纠?】Bill won39。t make any progress ________ he studies harder than before. A. so B. when C. because D. unless【解析】答案是D。根據(jù)句意結(jié)果是不會取得進步，四個選項的關(guān)系so所以，表示結(jié)果；when當……時候，表示時間；because因為；unless如果不，除非，表示條件。【例5】________ Tom ________ Mary is busy at the moment. You39。d better play with others．A. Both。 and B. Not only。 but alsoC. Neither。 nor D. Either。 or【解析】本題答案是B。首先根據(jù)動詞is busy單數(shù)形式可排除A選項動詞用復數(shù)。根據(jù)下文意思分析，此刻兩個人都很忙，不能和你玩。而C選項是否定意義，兩個人都不忙，D選項表示兩個人中有一個人忙，可以和你玩。這是極容易錯的典型題?！纠?】The cyclist held his raincoat tightly ________ the wind couldn39。t blow it away. A. so B. so that C. when D. because【解析】本題答案是B。首先要考慮上下文的關(guān)系，不是因果關(guān)系，所以排除A和D。緊緊抓住雨衣目的是為了防止刮走，而C是表示時間的連詞?！纠?】Peter was late for the meeting ________ he missed the ferry. A. though B. because C. while D. if【解析】答案是B。本句上下文是因果關(guān)系，上句是結(jié)果，下句表示原因，故用because。四個選項都是引導狀語從句的從屬連詞而不是并列連詞。though是轉(zhuǎn)折關(guān)系的從屬連詞；while用來表示轉(zhuǎn)折關(guān)系；if表示假設(shè)的條件，不符合句意?！纠?】 Which would you like to buy，a DVD player ________ an MP3 player? A. so B. or C. but D．a(chǎn)nd【解析】答案是B。本句是選擇疑問句，是“特殊疑問句，A or B?”結(jié)構(gòu)。提供兩種情況，詢問對方選擇哪一種?！纠?】Mr. Li is our teacher and friend as well.（保持句意基本不變）Mr. Li is ________ only our teacher ________ also our friend. 【解析】答案是not only…but also。根據(jù)句意，as well是“也是”的意思，而not only．．．but also是固定詞組，表示“不僅……而且”，與句意吻合。三、學法提煉1. 專題特定：連詞是選擇，完形中?？?。熟練地連詞使用，對寫作也有提升。2. 解題方法：連詞看似簡單實則易錯。特別要提醒同學注意的是必須掌握每個連詞的用法，認真仔細地思考、分析和判斷，這樣才能從四個選項中通過排除三個錯誤的選項選出正確答案。杜絕有些同學沒有經(jīng)過完整的思考，題目只讀到一半的時候就填寫答案。3. 注意事項：注意使用連詞后，哪些謂語動詞用單數(shù)，哪些用復數(shù)。課后作業(yè)作業(yè)1：整理錯題作業(yè)2：單項選擇1.
